Pi is an irrational number which can never be expressed as a fraction. It is popularly called the “infinite decimal” among Mathematicians.

Pi represents the ratio of the circumference of a circle to its diameter and no matter what size the circle is, the ratio will stay constant.

The current world record for reciting the most number of post-decimal Pi values was achieved by Rajveer Meena for reciting 70,000 digits in under 9.5 hours.

The number Pi has been around for longer than Christianity. Many records show that the Babylonians knew of Pi four millennia ago. They calculated pi as 3.125.
